Which approach to aquiring a system seems to be less expensive?

The less expensive approach to acquiring a system typically involves opting for off-the-shelf solutions rather than custom-built systems. Off-the-shelf products generally have lower initial costs, as they do not require extensive development and can be implemented quickly. Additionally, using existing software reduces the need for specialized maintenance and support, which can further lower long-term expenses. However, it's essential to consider potential limitations in customization and scalability.
